RESUMEN
Randomized, controlled trials (RCTs) have assessed the effect of colchicine therapy in prevention of pericardial effusion (PE) and atrial fibrillation (AF). However, the effects are still inconclusive. PubMed, Cochrane Library, Google Scholar, and EMBASE database were searched. Primary outcome was the risk of PE and AF. Ten RCTs with 1981 patients and a mean follow-up of 12.6 months were included. Colchicine therapy was not associated with a significantly lower risk of post-operative PE (RR, 0.89; 95 % CI 0.70-1.13; p = 0.33, I (2) = 72.8 %) and AF (RR, 0.77; 95 % CI 0.52-1.13; p = 0.18, I (2) = 47.3 %). However, rates of pericarditis recurrence, symptoms persistence, and pericarditis-related hospitalization were significantly decreased with colchicine treatment. In addition, cardiac tamponade occurrence was similar between groups, and adverse events were significantly higher in the colchicine group. Colchicine may not significantly decrease the post-operative risk of PE and AF. However, only limited studies about patients undergoing cardiac surgery provide data about PE and AF.
